It is a utility in ServiceNow to run scripts in the background, which is useful for mass creations, updates, and deletions of records. It is also greatly helpful in troubleshooting records and running complex scripts to find information. They can do complex operations in a short amount of time. A background script is generally used when you should run a script for a one time action, or when Admins need to run any cleanup jobs. Converting the background script to a scheduled script on demand gives more control.

In addition, you can also review the code later if required, which is not possible in a background script. You just type raw text, if there is an error you will only realise after the execution.

However, that is not the most efficient way to update data in certain cases. It might not be feasible to use the list editor to update K records or make a CSV file to update the records. Sometimes a background script can be created in minutes that solves the issue. Scenario: Admin needs a fast way to test server-side scripts without creating problem in the instance.

Due to the possible risks, there is not too much information available from ServiceNow for background scripts. Well, there are demo ServiceNow instances and your development ServiceNow instances. Be sure to try your Background scripts carefully before attempting on a Production ServiceNow instance.

Remember how I told you a few paragraphs back about how powerful background scripts are? I really mean this, They can cause: destroyed data, revoked access, or even system shutdown. If you are doing a glide record query and your query is not designed correctly, ServiceNow javascript will ignore the query and not produce an error.

Here is an example:. If I was doing a delete or update statement in the background script, this would not be good.

If you are doing an update statement in your background script. Comment out your update statement and add a RowCount statement until you are sure it is ok. When you ready to run that script and it is going to update the right number of rows, uncomment out the update line and run again. In 2 above, used a gs. However you can also use gs.

However whichever one you pick, they are both helpful to troubleshoot issues with your script or with just general troubleshooting. Here is an example on how to avoid this:. In the example above the setWorkflow and autoSysFields statements avoid those workflow and autoSysFields from being run or updated. This is really needed in cases when you are updating tasks and the last updated time affects an sla or the tasks that have a lot of business rules on them you want to ignore.

Scripts - Background was this magical place in the platform where you could run any server-side script.

It became my testing ground for any server-side method I wanted to learn about or new script I wanted to test because I did not need to configure When to run logic around it like a Business Rule. Running a script in Scripts - Background was as easy as putting a script in the field and clicking the Run script button.

I will admit that for most scripts I need to run on an instance these days, I prefer other ways to execute my scripts over Scripts - Background.

Syntax highlighting and checking are just too helpful for me to pass up if I have access to them. The value of Scripts - Background lies in its simplicity. No need to create a record. Just write or paste in a script and run it.

Free-form JavaScript can negatively impact data and system performance. In this post, you learn how to work with Scripts - Background to add some demo data. You also learn how to work with the rollback capability to remove the demo data.

Execute in sandbox? Refer to the documentation on The script sandbox property for details on what methods are restricted. Executing in sandbox can prevent potentially harmful methods from running, but could prevent the script from its intended purpose.

It is an utility in ServiceNow to run scripts in the background, which is useful for mass create, update, and delete of data. It is also greatly helpful in troubleshooting records and running complex scripts to find information.

Background scripts are very powerful and can do complex operations in a short amount of time. In ServiceNow, you can get around using background scripts by using these other methods. Using the List Editor. Importing Data to create, update, or delete records. However, that is not the most efficient way to update data in cases.

It might not be feasible to use the list editor to update K records or make a csv file to update the records. Sometimes a background script can be created in minutes that solves the issue.

Background Scripts are so powerful that you can cause major issues to your ServiceNow system with the right script. You need to be extra careful in running background scripts. Always test Background Scripts first in a development instance. Please read how to be careful with Background Scripts first, before you get into it:.

Remember how I said about how powerful background scripts are? I really mean this, I have seen data destroyed, access revoked, and system shutdown from background scripts. Here are a couple points to help you avoid unknown disasters with Background Scripts. If you are doing a glide record query and your query is not designed correctly, ServiceNow javascript will ignore the query and not produce an error.

Here is an example:. This is an honest mistake, but since that column doesn't exist ServiceNow will ignore the query and return all records. If I was doing a delete or update statement in the background script, this would not be good. If you are doing an update statement in your background script. Comment out your update statement and add a RowCount statement until you are sure it is ok.

With this example, it will return how many rows are going to be updated before you update. When you ready to run that script and it is going to update the right number of rows, uncomment out the update line and run again.

In 2 above, I used a gs. However you can also use gs. However either one you pick, they are both helpful to troubleshoot issues with your script or with just general troubleshooting.

An easy way to identify the encoded query string to use is to create a filter or a module with the query parameters you want to use, and then hover over the link or breadcrumb and look at the URL. Is there a way to query for a date?

Such as current. You can build the query you want in a module or filter definition to see what the encoded query should look like. SN seems to be all scripting from the get go with limited use of GUIs for configuration. Thanks for the comment. Hopefully some of the content here helps you to get going a little bit faster.

I know that the SNC documentation team is really focusing right now on scripting documentation so what you see on the wiki should be getting better by the day. You might check out these forum links for some more information about SNC scripting basics. In reference to the Or query — is there any documentation about what a QueryCondition object is, and what its other functions are?

There are a couple more examples that I could probably share though. I find the encodedquery to be extremely helpful especially when my query includes things like created this week or created before a specific date. Then I know for sure I have the right query string. Question: If I run a GlideRecord query and then want to add another condition to the query and rerun it, is that possible? Not that I would do the following but just as an example.

One thing to note about updating a reference field to null is that it has to be done as described here:. Thanks so much for posting this info -it is really helpful!. Here is an example of what we wre trying to accomplish. Did you ever determine a way to do it. The only other way I can think of doing it is to create two separate queries and then combine the results not very pretty but easy enough I suppose. However, if i leave the line as is, i wont see the update. Anyone have any thoughts?

This cheat sheet covers the most frequently used GlideRecord operations. All explanations and examples are easy to follow. It saved me huge amount of time which I may have spent looking through the Service-Now Wiki pages. Can you describe the scenario or area of the tool where this would be used? I know this was asked a long time ago but here is how you print the current query: gs. So I created an addEncodedQuery and it produced the correct data on the display list but any further filtering on the list is ignored.

There are some queries that doesnt seem to be in this post which is very nice to have. With Service portal — async GR is very wanted. Thanks very much for your suggestions — I am very much intrigued with the capabilities of these constructions.This is an extension on the article, Client and Server-side Programming.

That article discussed the differences between client and server-side scripts. In this article, I want to get into more detail with client scripts.

How they work, what they do, and many examples. Here is an example of a client script for this scenario. I wrote this just for the change of the Good field. However you probably would also want this for the fast and cheap fields.

That means you would need to also add scripts for those scenarios. This is one of the drawbacks of client scripts. I have a good example of a client script opening a GlideDialog window here.

ServiceNow UI Page and UI Macro

I am just going to show the client script part. In this example, a window pops up on form load. It is tempting to use this for many color changes in ServiceNow. How use Field Styles instead as much as possible. Before ServiceNow version Dublin was released, I used this to verify a phone number format.

Dublin has new phone number fields. However it is a good example of regex function. If you are not familiar with regular expressions, here are some explanations of what regular expressions. Use Field Styles for setting other field sizes. Callback functions make JavaScript far more flexible than it would be otherwise. Typical functions work by taking arguments as input and returning a result.

Functions take an input and return an output. Javascript callback functions are different. Instead of waiting for a function to return that result, you can use a callback to do this asynchronously. This not only helps with performance, it strongly encouraged to use callback functions and asynchronous programming. To learn all about client script GlideRecord queries, check out the ServiceNow wiki article. These are limited glide record queries you can use to make server-side database queries.

They use callback functions to do this. I always suggest using business rules instead for these, but sometimes I can't convince people to do that. It is better to use a GlideAjax query than a GlideRecord query. There is a good example in the wiki for that. View fullsize. For this example, we have five fields, Good, Fast, Cheap, and Result.
